Outline of Final Research Achievements

With the recent growth of internet and communication applications, increasing requirement for scalable high efficiency video coding (SHVC) encouraged the research for next generation coding standard. A specification and reference software about scalable extension of H.265/HEVC have been developed by the joint video team (JVT) for SHVC. Taking into account that the complexity of HEVC codec is higher than other existing standard codecs, its scalable extension is expected to be simpler with high coding efficiency. In this work, some novel algorithms are proposed and a pre-processing module is introduced to realize parallel processing. The pre-processing module can analyze the image features and select the optimal coding parameters that can significantly reduce the computational complexity of the rate-distortion optimization. This work achieved high coding efficiency with very hardware friendly architecture.
